1.2. Network Address Port Translation (NAPT, IP Masquerade) and N-8000 Software
Program
Because the Internet cannot be accessed using the local IP address, the local IP address must be converted
into global IP address by means of Network Address Port Translation (NAPT, IP Masquerade).

Connection can be made from Unit C to Unit A using the global IP address. The global IP address used for the
connection is converted into the local address for Unit A by Router 1.
The N-8000 Software program is designed for full compatibility with the NAPT (IP Masquerade).
When performing settings for the equipment connected by means of NAPT (IP Masquerade), tick the "NAPT
compatible" item displayed by pressing on the "Network setting tab" of the Exchange, Multi interface unit, or IP
station, and enter the router's IP address and Port No. (Refer to
p.5-25 , 5-33 and 5-45 .)
